There is more than one way to do it. One of them is outlined here. Objective is to have a lightweight model still looking realistic when zooming in. It is not meant to actually reflect the standard geometry or being fit for 3D printing.

  • Create a cylinder and add a chamfer to the tip

  • Create a cutting tool (sketch) and add a SubtractiveHelix to the part with appropriate settings for pitch and heigth. Make the heigth greater than actually required, then you can make longer bolts by just increase the height of the initial cylinder.

  • Add a cylinder (head)

  • Add the slot. First, a sketch is created on the top of the head, then this sketch is extruded removing material.

  • Add a local coordinate system and label it "LCS_bolt". The origin is at centerline at the interface between head and shaft. Z points towards the tip. The system is used to place the bolt in holes and to determine its length.
